Synthesis and in-vitro antimicrobial screening of 3-cinnamoyl coumarin and 3-[3-(1H-indol-2-yl)-3-aryl-propanoyl]-2H-chromen-2-ones
An efficient synthesis of some novel coumarin derivatives via 1, 4- Michael addition of indole to coumarin chalcones catalyzed by cellulose sulphonic acid (CSA) under solvent free conditions is described. The corresponding Michael addition products were obtained in good to excellent yield. The synthesized compounds were screened for their antibacterial activity against E. coli, S. aureus and an...

متن کاملPreparation and Characterization of Ti(BH4)3(THF)3 and V(BH4)2(TMEDA)2 Complexes
We have recently synthesized Ti(BH4)3(THF)3 and V(BH4)2(TMEDA)2 complexes. The reaction of TiCl3(THF)3 with NaBH4 in dry THF gave flat blue crystals, Ti(BH4)3(THF)3. The reaction of VCl3 with NaBH4 in presence of N, N, N', N'- tetramethyle...
متن کامل3. Multimodal Communication
1. Why is the topic of multimodal communication interesting? Face-to-face communication is the evolutionary primary and most common way of communicating for humans. It is not unlikely that vocal-verbal language with more or less intentional control, but still to some extent systematic, developed from being action-and gesture-based to being vocally based (Arbib 2005). In contrast to the hundreds...
